Abstract
An image forming apparatus and toner-consumption-estimation method that can accurately estimate the amount of consumed toner regardless of the type of image. A printing-pixel-counting unit counts from input image data the number of printing pixels. Also, an edge-counting unit similarly counts from the input image data the number of edges being boundaries between the printing pixels and blank pixels. A consumption-estimation unit then calculates the amount of consumed toner based on the counted number of printing pixels and the number of edges.
